How to Install Oracle Database 12c on RHEL/CentOS 7

Oracle database is one of the most widely used relational database management systems (RDBMS) in enterprise environments. Developed, maintained, and supported by Oracle Corporation, this RDBMS is often installed on top of a flavor of Enterprise Linux (RHEL, CentOS, or Scientific Linux). This makes for a very robust operating system – database choice.

In this article, we will explain how to install Oracle 12c Release 2 on a RHEL/CentOS 7 GUI server.

Additionally, please note that an Oracle account is required to download the Oracle Database 12c installation file (3.2 GB). Don’t worry about this, though, as you can create an account for free.

Finally, make sure your server has at least 2 GB of RAM and 30 GB of available disk space. These hardware requirements are safe for a testing environment such as ours, but will need to increase if you consider using Oracle in production.

Preparing for Oracle 12c Installation

1. To begin, make sure that all the packages currently installed on your RHEL/CentOS 7 system are updated to their latest versions.

# yum update -y

2. Next, installed all the required dependencies for the RDBMS, along with the zip and unzip packages.
